ASoC: spdif_transmitter: Allow 192kHz sample rate

Transmitters and receivers may support a 192kHz sample rate.

Tested with Cubox-i imx6 system and Onkyo TX-SR607 receiver.

NOTE: However, my S/PDIF transmitter was seemingly bricked at some
point during testing various code changes, and I can't be certain if
it was these high sample rates or something else.
This needs additional testing before it is applied anywhere.
